Sen. Davis must speak about the bill and related topics. No other senators can speak for her. Davis cannot leave the podium or drink water. And she will have to keep it up for until the senate adjourns tonight at midnight.

Davis said she would use up large chunks of time reading into the record testimony from women and doctors who would be impacted by the changes.

Davis' filibuster is an effort to present a vote on Senate Bill 5, which would ban most abortions at 20 weeks of gestation, require that abortions be performed in ambulatory surgical centers and require doctors who perform abortions to have admitting privileges at a nearby hospital. The measure also would require doctors who administer the abortion-inducing drug, RU-486, to do so in person.
